Ceil is precisely a mathematical function which takes in a number and returns back the smallest integer greater than or equal to that number.

More details

The ceil function is typically represented as ::\lceil x \rceil:: in mathematics, where ::x:: represents the number to be ceiled. For example, ::\lceil 10.001 \rceil:: evaluates to ::11::.
